PREFATORY STATEMENT. 


Every mental effort of inherent merit involving useful addition to the sum 
total of permanent human knowledge must have a definite aim and rest upon a 
fundamental basis. : 

The five volumes constituting this work and representing eleven years’ uninter- 
rupted labor of a small force is an attempt to cover in detail, by a line-upon-line 
index approximating seven hundred thousand entries, the chemical subject matter 
of all of the United States patents granted during the ten-year period January 1, 
1915 to December 31, 1924 (U.S. Official Gazetté, volumes 210 to 329 inclusive) ; 
being the 398,377 patents between the issued numbers 1,123,212 and 1,521,589, of 
which 22,882 separate patents have been indexed herein together with the re-issues 
which have been published during this time. It is intended adequately to cover the 
whole field of chemical technology—organic, inorganic, biological, mineralogical, 
- pharmaceutical, photographic—thus comprehending from a patentability point of 
view the entire industrial chemical development in both the warlike and peaceful 
arts during this decennial period. In the index of patentees comprising the first 
portion of this volume, 14,526 names are recorded as sole or joint inventors. 

No attempt has been made to edit, amplify, curtail, expurgate, interlineate, trans- 
pose or correct any statement appearing in the patents indexed for obvious legal 
reasons, the subject matter being indexed as is and without comment. In patent 
adjudication it repeatedly has been held by the Courts that the construction and 
intent of a specification must be judged by the actual published statements solely, 
i. e., what the patentee said, and not what one of supposed superior knowledge might 
infer he intended to mean, and that the specification description must be stated with 
sufficient lucidity, exactitude and comprehensiveness so that “one skilled in the art 
to which the invention appertains ” by following the description alone, may be able 
to obtain the result specified and/or claimed. The involved phraseology, obvious 
circumlocution, and deficiency in chemical knowledge apparent in the description of 
some inventions render their indexing in an intelligent and understanding manner 
a matter somewhat of guesswork. In such instances the context has been indexed 
as printed, and then again indexed the way we deduced the invention should read. 
This accounts, in a measure, for the extreme detail with which this Index has been 
subdivided. 

The present litigation in respect to the aryl-substituted guanidines as rubber 
vulcanization accelerators is indicative of how exhaustive an index of this nature 
should be in order to become of maximum utility in anticipatory searches and 
searches involving alleged “lack of novelty” in a chemical process, or product, 
or both. 

The method of preparation of this Index has been as follows: The description of 
each patent as printed in the Official Gazette was critically examined, and if it 
appeared from the statements therein that the patent might contain subject matter 
of a chemical nature, the patent was purchased. From this original patent, the 
chemicals and chemical manipulations and mechanical devices were indexed with 
sufficient completeness and fullness to cover apparently all of the chemical subject 
matter from any angle which might be sought, each item or line being placed on 
a separate card. These cards were then reviewed against the original patent. Instead 
of typing the patent number at the close of each line, the cards resulting from the 
indexing of each patent were rubber stamped with the patent number by means of 


6 PREFATORY STATEMENT 


a numbering machine, it having been found nearly impossible to write the same 
number of seven figures several times without transposition or other error in figures. 
These cards were then thrown strictly alphabetically, the duplicates under one 
heading combined on a single card, and the cards then re-typed introducing dashes, 
instead of phrases represented between adjacent commas. By the substitution of 
dashes instead of words and phrases, the bulk of this work has been reduced by about 
1260 pages without contraction of statement. This formed the original manuscript 
which was then re-read against the individual cards. In preparing the original cards 
(3” x 8” in size), they were typed by being fed continuously into a typewriter at 
distances of about 4 inch apart against a carbon sheet and a letter-size sheet under- 
neath, so that following each patent indexed there appears one or more sheets with 
a carbon of each line written upon the individual cards—an excellent method of 
afterwards checking as to'the accuracy and completeness of indexing of the individual 
patent. The number of cards thus prepared from a single patent ranged from one 
or two in the relatively unimportant ones, to several thousand cards. For example, 
from U. 8. Patent 1,505,043, which is a dissertation upon the cellulose ether art, 
there were prepared 2756 individual cards, the carbon of the same comprising 108 
typed letter-size sheets. The total cast to us of indexing this ten-cent patent exceeded 
one hundred sixty dollars. The patent and the carbon sheet (or sheets) of the cards 
pertaining thereto were then filed in a series of loose-leaf covers by numerically 
increasing numbers, the first number of the patent in the volume appearing on the 
back of the same. A library of 168 volumes was thus formed covering this period. 

It will be observed that a question mark has been placed in parenthesis in various 
places in the Index, indicating that while the patent has been indexed as published, 
we demur as to the completeness, clarity, accuracy or propriety of the statement 
so indexed. 

In the indexing of the patents of the decennial period 1905-1914 we are now 
engaged, as likewise upon the biennial period 1925-1926. It is hoped to keep the 
Index to date by the issuance of biennial volumes, and if the demand for a work of 
this character is commeasurable with the labor and expense involved, it is planned to 
continue working backward in series of volumes embracing the periods 1885-1904 
and 1790-1884, thus eventually making the Index complete for the entire United 
States patent issuance. It appeals to us that such a series of volumes, if accurate and 
complete, would be a wonderful stimulus to chemical patent inventiveness and 
ingenuity in the United States; would minimize useless legislation based on faulty 
or inadequate information as to the extent of basicity of chemical patents already 
allowed ; indicate almost at a glance in an authoritative manner the precise state of 
the patent art for any given subject; and would substantially replace the laborious 
and not always satisfactory methods of search now available, at present based 
primarily upon systems of classification. We believe a patent index of this nature 
should be far superior in accuracy and completeness to the methods of patent 
search now available, provided the index is accurate, exhaustive and of maximum 
availability, for the reason that such a work indexes the subject matter from a 
line-upon-line scrutation of the specification and claims—the actual “guts” (a 
polite word in Shakespeare’s time) of the patent—and depends in no wise upon the 
heading or claims only, which are often intentionally (?) involved and misleading 
for a definite purpose in the mind of the patentee, the real essence of the invention 
being perhaps hidden in an unobtrusive paragraph, and phrased in an inconspicuous 
manner, presumably with a well-defined purpose in view. There are said to be 
“ tricks in all trades.” In this connection we classify the preparation and searching 
of chemical patents as a “ trade,” and for this and other reasons, the preparation of 
an adequate index of the entire gamut of chemical technology has involved much 
labor on our part in certain instances, in endeavoring to try to satisfy ourselves as to 
the breadth, scope, basicity and limitations of a given invention from perusal of the 


PREFATORY STATEMENT v 


specification context. In some instances we have obtained and read the File Wrapper 
from which the application eventuated into a patent, in order to clarify our own 
mind upon involved points. It would seem that some of the granted specifications 
must have been prepared by “ specialists,” if a specialist is one “who knows more 
and more about less and less.” 

Upon Leo Rutstein, our junior associate, who collaborated in the preparation of 
the Author’s former volumes, has devolved the responsibility of correlating the 
various systems of nomenclature and methods of procedure in indexing, in evolving 
a system applicable in maximum usefulness in an index of this character, which is 
composed of a non-homogeneous mixture of terms used in pure chemistry, chemical 
technology and chemical expressions of the trade and the works. The system of 
nomenclature used in Chemical Abstracts, Beilstein, “ Organische Chemie” and 
Richter and Stelzner, “ Lexicon der Kohlenstoff Verbindungen ” has been followed 
by combination.. In general, letters and phrases enclosed in parentheses are not to 
be considered in alphabetization. Letters and words in italics such as 0, m, p, d, l, 
leuco, racemic, etc., are not to be considered from an alphabetical standpoint. 

The numbering used in organic compounds is that followed by Chemical Abstracts, 
as far as it was possible to do so. The name used is of the largest parent compound 
it 1s possible to use for maximum clarity and to show the chemical structure. 
Thus 3-amino-hydroxy-benzene-sulfonic acid is hydroxy-metanilic acid. The name 
“ phenol-sulfonic acid ” is not used, save in a few exceptions. The only name used 
which indicates two functions is Naphthol-sulfonic acid, and in numbering these 
derivatives, the naphthol is always 1-naphthol or 2-naphthol, other groups being 
numbered to correspond. This is of paramount importance as several systems of 
numbering are used in the patents, and the same compound may appear under three 
or four separate headings. This heterogeneity has crept into the Patent Office 
archives mainly as the result of foreign patents being applied for in verbatim 
language to the foreign application, or having been translated into English in the 
country of their origin for filing here. 

All substituent groups are listed in strictly alphabetical order and not in the order 
in which they may occur in a homologous or isologous series, and include such poly- 
compounds as dimethyl and triethyl, which are listed as one group beginning with 
“d” and “t” respectively. For example, substituent groups herein are written in 
the following order: Amino-chlor-diamino-dibenzyl-ethyl-methyl-phenyl-ete. This 
is of importance as otherwise it would be impossible to tell which of the substituent 
groups came first in the name, and consequently the card or entry could be located 
only with difficulty. Amyl-butyl-ethyl-methyl-octane would be found as above, and 
not this combination beginning with (say) butyl, or ethyl, or methyl. The same is 
true when using the largest parent compound, as in the case of hydroxy-metanilic 
acid, cited above, the compound if written in one way would be found under 
“Amino-etc.,” whereas it should be found under “ Hydroxy-metanilic acid.” For 
this reason a large number (about 3800) “see” and “see also” cards have been 
used in order to clarify, simplify and knit together the Index into a compendium of 
maximum usefulness and speed of reference. 

The use of bis-, bi- and di- is that given in Chemical Abstracts. For instance, 
nearly all compounds which might approximately be called Di...... -methane, are 
listed herein as Methylene-bis...... A complete explanation of this matter is 
found in the Journal of the American Chemical Society 1917, vol. 39, page 1623. 

There are many articles and processes for which a large variety of words could be 
used as the index or leading word with equal propriety. We have endeavored to 
select as the “key” word or expression, that probably most familiar to a chemist 
or patent attorney, or the word or phrase most expressive of the thought in the 
least number of letters or words, in order to reduce the bulk of the Index to the 
minimum compatible with clearness. 


BUSY PREFATORY STATEMENT 


Most of the names are self-explanatory to those reasonably familiar with the 
particular subject involved. Names of minerals are based on Dana’s Mineralogy, 
those of pharmaceuticals and medicinal chemicals and therapeutic synthetics on the 
last edition of the U. S. Pharmacopeeia and the two Dispensatories. The name used 
in the heading of the entry is the preferred English name for the product. 

To research workers and authors, attention is directed to the wealth of data con- 
tained under the respective headings of the various topics. As a citation, under 
“ Benzaldehyde” are to be found on pages 727-729, a total of 258 citations of 
patented information under 229 separate headings. 

An inventor, through lack of chemical knowledge, or in an attempt to broaden 
the scope of his invention, or cover up the real essence of the specification, often 
indulges in generic rather than specific terms or expressions upon which two or 
more constructions may be placed, thus rendering the proper indexing of the patent 
difficult. If one is interested in (say) arsenous oxide (arsenic trioxide) the data 
may be found partially under “arsenic,” which is supposed to index only the 
elemental form, but undoubtedly has therein many references to the arsenic oxides, 
especially the trioxide. He should also consult “ arsenous oxide,” “ arsenic trioxide,” 
“arsenic oxide,” “arsenious acid,” “arsenic acid,’ and “arsenic pentoxide,” for 
the reason above stated. Then there are present in this Index a number of general 
headings such as “ arsenate,” “arsenite,” “article,” which would be superfluous if 
the patent were sufficiently specific from a chemical viewpoint, or if the inventor 
were not endeavoring to protect for himself a whole series of compounds, rather than 
a specific body in a general class. When examining the references under a specific 
heading, always at the end of the references refer to the heading for leads under 
“see ” and “see also” referencs in italics. 

In comprehending the entire U. 8. patent art covering the period of this Index for 
any given subject, if the Index is complete, it merely becomes necessary to order 
of the Commissioner of Patents, Washington, D. C., at ten cents each, the patents 
represented by the numbers appearing under any given subject. That is, this Index 
_ 1s supposed to be a complete search of the entire field of chemistry as shown by the 

granted patents and patent re-issues. 

The abbreviations used in this work are few and simple: “ mfr.” for manufacture, 
manufactured or manufacturing (whichever is most applicable) ; “ obtg.” for ob- 
tained by, obtaining; “contg.” for contained, containing; “ pro.” for production, 
producing. 

As an example of the use of dashes instead of words, attention is drawn to the 
seventeenth line from the top of page 250, which says: “—, —, —, mfr. of, process,” 
and which would read in full, “A process for the manufacture of alcohol by the . 
oxidation of air in the presence of a catalyst.” 

We have roughly computed the extent of the four succeeding volumes covering 
this decennial period Index of chemical patents by weighing the cards and headings 
comprising the same, and comparing them against the weight of the cards contained 
in this volume. The approximations are as follows: 


Vol. I. Preface and Index of Names, 138 pages; Subject Index, A-497; 
B-269. Total 904 pages. 

Vol. II. C-6%5; D-110; E-105. Total 890 pages. 

Vol. III. F-200; G-135; H-125; I-140; JK-35; L-145. Total 780 pages. 

Vol. IV. M-205; N-120; 0-90; P-355; QR-130. Total 910 pages. 

Vol. V. S-460; T-160; U-20; V-70; W-110; X-12; Y-10; Z-70. Total 912 
pages. 


This gives an apparent approximation of 4396 pages for the five volumes. 


PREFATORY STATEMENT 9 


It is a pleasure to acknowledge and to record the valuable assistance of the 
coadjutors who have co-operated in the arduous labor involved in some portions of a 
work of this character, who have contributed of their time, energy and specialized 
information so willingly, and without whose assistance the work could not have 
eventuated. If there is merit herein, the credit primarily to them belongs. Preston 
R. Smith, expert in the intricacies of organic chemistry; Dr. Carl Marx, Dr. O. W. 
Wilcox, and Messrs. De Witt Bell, Clarence H. Lehman, John W. Bruce and Clifford 
Evers are all entitled to special acknowledgment. Mr. George H. Stevens kindly 
looked over those portions of the index involving rubber and vulcanization acceler- 
ators, and allowed us to draw from his years of practical experience in the elucidation 
of this complicated subject. Mr. Frank Alva Worden threw the entire list of cards 
into the approximately 5780 separate indexing headings constituting the original 
card classification, a task involving nearly four years of uninterrupted labor and 
calling for a high degree of sustained perseverance. 

Tio Misses Jean N. Baker, Lydia Englander, Pauline 8. Newmark and Sophia R. 
Livingston, A. B. (in order of their seigniory), have devolved the responsibility of 
spelling and card classification, the retyping of the cards upon sheets with the 
replacement of words and phrases by the corresponding number of dashes, and the 
almost endless checking of the references against the original patent specification to 
ensure the minimum of inaccuracy. 

Grateful appreciation is acknowledged to the technical staff of the Chemical Cata- 
log Company, Inc., for valuable assistance during the progress of the planning and 
printing of the work, and to The Lord Baltimore Press, of Baltimore, Md., for the 
execution of what must be conceded to be an unusual and difficult piece of typog- 
raphy. This point becomes especially pertinent when it is remembered that the 
entire work, from issuance of first galley proof to the completion of. printing, 
occupied a period of less than nine weeks. 

The Author would esteem it a courtesy to have his attention directed to such errors 
as have inadvertently (or otherwise) crept in. Pending the issuance of succeeding 
volumes, correspondence respecting data not yet published will be welcomed from 
those interested in topics which happen to begin with letters other than “A” or 
“B” comprising this volume.
